Abstract

The aim of this study is to assess epididymal sperm morphology in cats under natural photoperiod. Mixed breed tomcats (n=43) that underwent bilateral orchiectomy at a municipal public pet shelter were used in the study. Only mature toms castrated in the two lasts weeks of each season were included in this study. Sperm samples were obtained by cutting the cauda epididymis and stained with tinción 15® (Biopur). Toms castrated during increasing light season had higher normal sperm morphology compared to toms castrated during decreasing light (45.95 ± 2.5 vs. 35.95 ± 3.4; P<0.02). Likewise, a higher percentage of head sperm abnormalities were observed during decreasing light season compared with increasing light period (17.27 ± 1.94 vs.10.73 ± 1.04; P<0.05). In conclusion, natural photoperiod induces seasonal changes in sperm morphology.
